CRANK CASING FOR INTERNAL-COMBUSTION ENGINES.

Application filed August 18, 1924. Serial No. 732,741.

To all whom t may concern.:

Be it known that I, PARKER B. HASKELL, a citizen of the United States of America, and a resident of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improve-` ments in Crank Casings for Internal-Combustion Engines, of which the following is a. specification.

This invention relates to crank casings for internal combustion engines and has for its object the provision of means whereby the oil in the crank troughs may be quickly changed and the sediment therein removed.

These objects are attained by the mechanism illustrated in the accompanying drawing.

For the purpose of illustrating the invention, one preferred form thereof is shown in the drawings, this fo-rm having been found to give satisfactory and reliable results, though it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized and that the invention is not limited to the precise arrangement and organization of the instrumentalities as herein shown and described, except as required by the scope vof the appended claims.

Of the drawings:

Fig. l'represents a plan of crank casing embodying the principles of the present invention.

Fig. 2 represents a side elevation of the same with one of the oil `troughs removed.

Fig. 3 represents a vertical transverse sec? tion on line 3, 3 on Figs. 1 and 2.

Fig. 4 represents a horizontal section of one of the removable oil troughs, on line 4, 4 on Figs. 3 and 5, and

Fig. 5 represents a vertical transverse section ofthe oil troughs on line 5, 5 on Fig. 4.

Similar characters indicate like parts throughoutthe several figures of the drawing. n Y

In the drawings, 10 is a crank casing preferably provided with a bonnet, which, as it forms no-part of the present invention, is not shown in the drawings. f

The casing 10, as illustrated in the drawings, is adapted to contain four cranks 11 of an internal combustion engine, `one of said cranks 11 being shown in Fig. 3 of the drawings as secured to a crank shaft 12 and having the usual connecting rod 13 pivotally connected to its free end.

Beneath each crank 11 is disposed an oil trough 14 adapted to be partly lilledwith oil through which the free end of crank 11 must pass as the crank shaft 12 revolves, thereby thoroughly lubricating the bearings between the crank 11 and the connecting rod 13.

1t is usual to provide crank casings with such oil troughs or pans 14 but these pans er troughs 14 are liable to have sediment collect therein which is very objectionable.

Consequently, the troughs or pans 14 must be cleaned out from time to time and thle old oil replaced by a fresh supply of oi To do this, it is ordinarily necessary -to take the crank casing 10 apartl i'n order to gain access to the oil troughs 14.

This takes considerable time and requires the services of expert labor.

It is particularly objectionable when the crank case is a part of the installation of a fire truck or some other emergency vehicle which is liable to be suddenly called into service.` v

For instance, in some motor vehicles, it takes several hours to disconnect the crank case, takeout the oil pans, remove the sediment and oil from said pans', lill them again and then assemble the crank casing.

Should an alarm be sounded when this operati-on isv being performed, this particular apparatus could not respond to the call until the work was completed.

This is manifestly a great objection and the present invention is made to overcome this diliiculty and make itlpossib-le to accomplish the work piecemeal with a minimum amount of labor and in a very short time.

This desired resulty is accomplished by the following means: v l

One side wall of the casinor 10 has a nnmber of-openings therein, preferably one for each crank 11, and through these openings 15 are inserted the troughs 14 so that there will be one under each crank. v p

The inner end of each trough 14 has a depression or recess 16 in its wall into which extends a projection or lug 17 preferably formed upon the inner face of the rear wall of said casing 10.

The inner end of the trough or pan 14 is properly positioned by said lug 17 in the recess 16 and all vertical or lateral movement of said inner end is effectually prevented. Y

The outer end of each trough 14 is provided with a flange 18'V adapted to bear against a flat face on the front wall of the casing 10 and be secured thereto by bolts 19 passing therethrough into the front wall ofthe casing 10.

Each trough 14 has a depression 2O in the bottom thereof 'in which the sediment is adapted to collect.

lVhen it is desired to replace the oil in a trough or pan 14 the securing` bolts 19 may be removed, and the pan 14 taken out of the casing 10 through its opening 15.

The sediment and oil therein may be quickly removed from the pan, which may then be refilled and returned to its original position, all without disturbing the casing 10 itself, or the other troughs v14.

In other words, one trough 14 may be removed at a time and if an alarm is sent in, all that it is necessary to do is to immediately replace the trough 14 in the casing 10 and secure it in position.

The fire truck will then be ready for im mediate use. The other troughs 14 may be successively removed, each preferably being replaced before another is disconnected from the casing.

Obviously this is of great advantage.

It is sometimes desirable to remove the sediment from the troughs at more frequent intervals than it is necessary to refill the troughs with a new supply of oil and therefore provision is made whereby this may be accomplished.

The means employed to obtain this resuit is as follows:

Each depression 2O has a valve member 21 therein, said member being cylindrical with an elongated slot 22 extending diametrically therethrough.

Ordinarily, the slot 22 is vertical so that the sediment in the trough 14 may settle in this slot.

sages 23, 24 connected to the depression 2O by ports 25, these ports being alined and adapted to register with the opposite ends of the slot 22 when the said slot has been moved into a horizontal position.

The outer ends of the passages 23, 24 are under normal conditions closed by plugs 26 threaded thereto.

The valve 21 is adapted to be rotated by the head 27 on the front end thereof.

When it is desired to remove the sediment without removing the troughs 14, the plugs 2 6 are removed and air blown through the passage 23 into the slot 22, the valve member 21 having been rotated' sufficiently to aline it with the ports 25.

This injecting of air under sufficient pressure will force the sediment in the slot 22 into the passage 24 from the outer -end of which it will be discharged into any suitable receptacle provided to receive said sediment. i

Vhen this sediment has all been removed, the valve 21 is 'again f'turned to cause the slot 22 to assume a vertical position and the plugs 26- are Vreturned to their' places.

It will be noted that while the sediment is being blown out, the valve 21 is in such position that none of the air will be admitted to the interior of the trough itself.

By means of this invention the oil troughs 14 may be quickly removed separately from the casing and refilled with a fresh supply of oil after the sediment has Vbeen removed from said troughs, or if they oil in the troughs is still in fairly good condition except for the sediment which has collected in the depression 2O in the bott-om of the trough, this sediment may be readily 'removed without disconnecting lthe oil troughs from the casing 10.

The operation and many advantages fo'f the invention will be apparent without further description.
